As global borders become increasingly fluid and people seek greater mobility, dual and multiple citizenships are more in demand than ever. In 2025, one path to a second passport stands out not only for its legitimacy but also its emotional resonance: citizenship by descent. This option allows individuals to reconnect with their ancestral roots while gaining tangible benefits like visa-free travel, economic opportunity, and even enhanced quality of life.
Whether it’s for work flexibility, retirement plans, or a deeper connection to heritage, many are exploring their genealogical records with new urgency. Governments around the world are also revisiting and streamlining policies to meet growing interest, making 2025 an ideal year to apply.
Understanding Citizenship by Descent: What It Means
Citizenship by descent is a legal pathway to acquiring nationality through ancestral ties—typically through one’s parents, grandparents, or even great-grandparents. It differs from citizenship by naturalization, which generally requires long-term residency, and from citizenship by investment, which often demands a financial contribution.
For many, this route offers a unique way to gain citizenship without uprooting their lives or making substantial monetary investments. Importantly, it also fosters a reconnection with cultural identity, language, and tradition—elements that other pathways don’t always provide.
General Eligibility: Who Can Apply for Ancestral Citizenship?
Eligibility for citizenship by descent varies significantly between countries, but some general principles apply. Most nations require that at least one parent or grandparent was a citizen of the country in question at the time of the applicant’s birth. Some go further back—allowing claims based on great-grandparents or even earlier generations, especially if official records exist.
Required documents typically include:
- Birth certificates (for each generation in the lineage)
- Marriage certificates
- Proof of non-naturalization (e.g., ancestors who never renounced their original citizenship)
- Government-issued IDs or passports
Accuracy, authenticity, and proper apostille certification are critical when assembling your file.
Italy: Embracing Generations of Emigrants
Italy remains one of the most generous countries when it comes to citizenship by descent. There’s no generational limit—if you can prove an unbroken bloodline and your ancestor did not renounce Italian citizenship before the next generation was born, you may qualify.
Key rules for 2025:
- Citizenship can pass through the paternal line with no limit on generations.
- For the maternal line, eligibility begins only if the child was born after January 1, 1948.
- You must provide a comprehensive document trail from the Italian ancestor to yourself, including evidence of their emigration and naturalization status.
Applicants can apply either in Italy or through a consulate abroad, though wait times vary drastically depending on location.
Ireland: The Grandparent Rule Still Holds Strong
In Ireland, citizenship by descent remains popular, particularly among Americans, Canadians, and Australians with Irish roots. The primary mechanism is the Foreign Births Register, which allows individuals with an Irish-born grandparent to claim Irish citizenship.
Key 2025 considerations:
- If one of your grandparents was born in Ireland, you are eligible—even if your parent was not.
- If your parent was born outside Ireland but registered in the Foreign Births Register before your birth, you’re still eligible.
- All applicants must now submit additional documentation proving continued family ties and intent to maintain a connection to Ireland.
With Irish citizenship comes EU citizenship—offering freedom of movement across 27 countries.
Poland: Reclaiming Roots in Central Europe
Poland is unique in that it recognizes citizenship by descent even without formal registration—if an ancestor was a Polish citizen and did not lose that status, you may already be considered a citizen.
Eligibility hinges on:
- Proving that your ancestor left Poland after it became an independent state (post-1918)
- Showing that your ancestor did not acquire another citizenship before 1951 or otherwise lose Polish nationality
- Demonstrating a clear lineage with uninterrupted citizenship transmission
In 2025, the Polish government continues to streamline processing, making it easier to obtain recognition, especially for descendants of Holocaust survivors and WWII refugees.
Germany: Limited Yet Expanding Access
Germany traditionally has strict descent laws, but major reforms in recent years have expanded access. In particular, Germany has rectified historical injustices that denied Jewish families citizenship during the Nazi era.
Notable 2025 updates:
- Descendants of victims of Nazi persecution (including children, grandchildren, and great-grandchildren) may be eligible regardless of where they were born.
- Applicants no longer need to give up existing citizenships to claim German nationality.
- In some cases, descendants of German mothers (who lost the ability to pass on citizenship prior to 1975 reforms) may now be eligible retroactively.
Other Notable Countries: Portugal, Hungary, and Lithuania
Several other countries offer compelling routes to citizenship by descent in 2025:
- Portugal: Especially open to descendants of Sephardic Jews expelled in the 15th century. While the process has tightened, it’s still a viable route if you can prove lineage and community ties.
- Hungary: Offers citizenship to individuals with Hungarian ancestry, especially if they can speak basic Hungarian. The process is relatively fast and doesn’t require residency.
- Lithuania: Allows descendants of Lithuanian citizens who left before 1940 to apply. Documentation requirements are strict but manageable with archival help.
Each of these countries presents a distinct cultural and historical pathway—ideal for applicants seeking both legal rights and a deeper sense of belonging.
Final Steps: How to Start Your Citizenship by Descent Journey in 2025
If you believe you may be eligible, 2025 is an excellent year to act. Here’s how to begin:
- Research your family tree to identify any links to countries offering citizenship by descent.
- Collect Documents: Birth, marriage, and naturalization certificates for each generation. Certified translations may be required.
- Work with Experts: Many applicants find it helpful to consult legal professionals or genealogists, especially for countries with complex rules.
- Apply Through the Right Channel: Depending on the country, applications can be submitted through consulates, embassies, or directly within the country.
Keep in mind that while some applications can be completed in a year, others (especially in high-demand countries like Italy and Ireland) may take several years. However, once granted, citizenship can be passed to future generations—making it a lasting legacy.
Conclusion
Citizenship by descent is more than just a passport—it’s a bridge to your past and a gateway to future opportunities. In 2025, with updated policies and growing accessibility, there has never been a better time to explore your roots and claim what might already be rightfully yours.
